Unable To Access Tab Settings After New Installation

I am not sure I will be able to replicate the issue but the attached patch should fix it.

Thanks for taking a look at the issue so quickly. I gave the patch a try but unfortunately the issue still exists. It seems that array field $build['#attached']['library'] already exists as a string (and thus it won't be overidden). Here is a customized change I made:

  public static function attachLibraries(array &$build) {
    $build += ['#attached' => []];
    $build['#attached'] += ['library' => []];
    file_put_contents(__DIR__ . 'log.txt', var_export($build['#attached'], true));
    // ...
  }

The log contains the following:

array (
  'library' => 'core/drupal.dialog.ajax',
)

I took a look at Drupal core and noticed the following MR created for issue #2253257 📌 Use a modal for entity delete operation links Fixed (Use a modal for entity delete operation links):

https://git.drupalcode.org/project/drupal/-/merge_requests/3700/diffs#8d...

And, here is the merged commit for that issue:

https://github.com/drupal/drupal/commit/bab4e14492b807364137f4b4075c86cb...

Hope it helps.

That helps a lot.

The below code is a mistake coming from Drupal Core.

        '#attached' => [
          'library' => 'core/drupal.dialog.ajax',
        ],

...it should be...

        '#attached' => [
          'library' => ['core/drupal.dialog.ajax'],
        ],

You should file a new major issue and add a note to 📌 Use a modal for entity delete operation links Fixed .

For now, I can provide a reasonable patch workaround.

After applying the patch I get this error Warning: Undefined array key "#attached" in Drupal\webform\Utility\WebformDialogHelper::attachLibraries() (line 64 of modules/contrib/webform/src/Utility/WebformDialogHelper.php). So I added a fix to this patch. My core version is 10.1 and webform "drupal/webform": "^6.2@beta".
